Finally I got the opportunity to try this Zagreb restaurant too. It is indeed recommendable.
Although continental Croatia is rather based on "meat_dishes", this very local restaurant offers much more. Frequently visited by tourists and locals the same, one can´t actually make a mistake in the dish choice here. With the wines I would stay with the house wine, since the price is acceptable. The rest of the wine card I would try per glas (it may happen, that not all offered is available also). Major suprise to me was my choice of fish - they actually had a fresh St. Peter´s fish! Marvelous, not even in Dalmatia one can find it easely, since this fish is not breeded but caught at open sea. Since the dishes are made freshly, a larger group may wait a little longer - but it is definitely worthwhile!
